This year's Microsoft and Xbox's E3 media briefing will be held on Sunday, June 9 at 1PM PT / 4PM ET.
According to the hard-working team at Microsoft, the conference will be their biggest E3 presence ever and they "can’t wait to share more about what we’ve got up our sleeves for the future. Whether you play your games on Xbox One or on a PC, are fans of RPGs, first-person shooters and everything in between, or just like watching others play games, there will be something for everyone at E3."
As always, the show will be livestreamed on the Xbox Mixer Channel or on the Mixer app for Xbox One and Windows 10 (and probably YouTube, Twitch, and many others), giving you a chance to "check out everything from trailers for unannounced titles coming in 2019 and beyond to in-depth looks at previously announced games," including Gears 5, Halo: Infinite, and Ori and the Blind Forest.
Considering that Sony has already revealed the first details on PlayStation 5, E3 2019 might be our first good opportunity to learn more about the long-rumored successors to Xbox One, reportedly condemned Xbox Anaconda and Scarlett, two machines that apparently will hit stores in mid-2020.
